How this table was made: each figure comes from the maker's own US product page or manual, or from the reviewer named next to it, checked 2026-11-08. Dealectric does not test units itself. Rows with a Buy link are products Dealectric lists: the links are affiliate links, and their codes are re-tested in the brand's own cart every day (last check 2026-11-13).

What the differences mean

• Continuous power per battery. Pytes V5: 75 A × 51.2 V = 3,840 W at its recommended current, or 100 A × 51.2 V = 5,120 W at the maximum in its feature list. EG4 LifePower4 V2: 100 A × 51.2 V = 5,120 W. Epoch V2-T Elite: 80 A × 51.2 V = 4,096 W. A 5 kW inverter running near full load needs two Pytes or two Epoch batteries in parallel.
• Price per kWh of capacity (2026-11-08). Pytes V5: $1,450 ÷ 5.12 kWh = $283. Epoch: $2,599 ÷ 5.12 = $508. LiTime 48V 100Ah Bluetooth: $899.99 ÷ 5.12 = $176. Redodo kit: $1,149.99 ÷ 5.12 = $225, charger and monitor included. Vatrer kit: $1,579.99 ÷ 5.376 = $294, charger and LCD included.
• Rated lifetime energy. Pytes: 5.12 kWh × 90% DoD × 6,000 cycles = 27,648 kWh to 70% capacity at 25 °C, or $1,450 ÷ 27,648 = $0.052 per kWh. EG4: 5.12 × 80% × 6,000 = 24,576 kWh, with no end-of-life capacity stated. Epoch: 5.12 × 3,500 = 17,920 kWh at most, to 70% capacity with DoD not stated, or $2,599 ÷ 17,920 = $0.145 per kWh.
• Largest bank. Pytes: 16 × 5.12 kWh = 81.92 kWh per group, and up to six groups with a hub. EG4: 64 × 5.12 = 327.68 kWh. Epoch: 16 × 5.12 = 81.92 kWh, in parallel only.
• What the warranty years cover. EG4's 10 years are prorated 1/10th per year after the first year. Epoch's 11 years mean free repair or replacement in years 1–5, then 40% off MSRP on a replacement through year 11. Pytes states 10 years.

Your system	Fits	Why
Victron MultiPlus or Quattro with a Cerbo GX	Pytes V5	The only battery here that Victron has tested. It needs BMS firmware 1.10.18 or later.
EG4 18kPV or 12kPV hybrid	Pytes V5, or EG4 LifePower4 V2 when in stock	Both have a UL 9540 pairing with the 18kPV, and Pytes also has one with the 12kPV.
Adding to an existing LifePower4 V1 bank	EG4 LifePower4 V2	EG4 allows mixing if the V2 is the master and the V1 runs firmware v3.40.
Victron boat or RV that charges below freezing	Epoch V2-T Elite	Its heater lets it charge from -22 °F, and it is IP67. Its Victron link is Epoch's own claim.
Golf cart, lowest kit price	Redodo 48V 100Ah kit	Battery, 18 A charger and 500 A shunt monitor in one box
Club Car with hills or heavy loads	Vatrer 48V 105Ah Club Car kit	200 A BMS, 600 A for 3 s, UL 2271 named
Open-loop off-grid bank on a budget	LiTime 48V 100Ah Bluetooth	$176 per kWh, 100 A continuous, up to 4 in parallel

Which 48V LiFePO4 batteries Victron has tested

Victron keeps a list of batteries it has tested for closed-loop control with its inverters. The page was last changed 2026-09-23. Pytes is on it. EG4, Epoch, LiTime, SOK, Redodo and Vatrer are not. Victron also writes that "many additional 3rd party batteries are also compatible" and that using them "is permitted under warranty". A brand missing from the list means Victron hasn't tested it, not that it is barred.

What Victron requires for Pytes: Pytes BMS firmware 1.10.18 or later (shown as v18.1 on the GX and VRM), GX firmware v3.31, and VE.Bus firmware 469 (Multi RS 1.16). The hookup is the VE.Can to CAN-bus BMS type A cable (ASS030710018) with a VE.Can terminator, with DVCC on and SVS and STS off. Victron's Pytes page links the V5/V5A manual. Victron says Pytes firmware older than 1.10.18 still connects but is unsupported and may cycle between charging and discharging at 100% charge.

Victron support that comes only from the maker: Epoch says the V2-T Elite talks CAN at 500 kbit/s to a Cerbo GX, Ekrano GX or Cerbo GX Mk2. It names no other inverter link, rules out series wiring and allows up to 16 matched units in parallel. LiTime sells a 48V 100Ah Smart ComFlex ($1,097.99 at LiTime, 2026-11-08) that it calls plug-and-play with Victron. Both may work, but neither is on Victron's list.

EG4 LifePower4 V2: it has CAN and RS485 ports, a six-position DIP switch for the inverter protocol, and closed-loop support for up to 64 batteries. Its UL 9540 certificate covers it only as an energy storage system with the EG4 18kPV. On EG4's forum, an EG4 admin says a V2 can share a bank with a V1 only if the V2 is the master and the V1 runs firmware v3.40. Signature Solar listed it as unavailable on 2026-11-08.

Golf-cart batteries report over Bluetooth or a bundled display, not to a solar inverter. LiTime's "200A" model holds 200 A for 2 minutes (2C). LiTime's standard 48V 100Ah is rated 100 A continuous with a 600 A one-second peak. The $1,149.99: https://dealectric.com/go/redodo-48v-100ah-golf-cart-conversion-kit comes with its charger and a shunt monitor for $1,149.99. The $1,579.99: https://dealectric.com/go/vatrer-48v-105ah-club-car-golf-cart-battery-kit costs $1,579.99 and adds a 200 A BMS and a UL 2271 listing.

Not recommended

Epoch 48V 100Ah V2-T Elite for a home solar rack. At $2,599 it costs $1,149 more than the Pytes V5. It is rated 80 A continuous, and its 3,500 cycles are rated to 70% capacity. It talks only to Victron GX devices, cannot be wired in series, and its page lists cell-level UL 1642 and UL 9540A, not a pack-level UL 1973. It makes sense only for a Victron boat or RV that has to charge below freezing or needs IP67.
