Professional Energy Storage Battery Pack Supplier

As lithium-ion batteries gradually replace lead-acid batteries in essential applications such as electric vehicles and energy storage, safety concerns continue to be a major issue. At Bofit Technology, we understand the importance of safety in lithium-ion battery applications and have chosen lithium iron phosphate (LiFePO4, or LFP) as the chemistry for our products.

With the principle of “Safety Above All” in mind, Bofit is dedicated to providing top-quality low voltage energy storage battery packs. Our team of professional engineers, optimized supply chain, and regional agencies allow us to provide prompt services to our customers.

Unlike other suppliers, we understand that safety is a top priority. That’s why we exclusively use the safest chemistry for our batteries. At Bofit Technology, we believe in a safer tomorrow.

Dear customer, the 100ah lifepo4 battery dimensions:12.95*6.77*8.42inch/329*172*214mm, weight:24.2lb/11kg.

48v max via 4 batteries in series. That is the max. You’d need 2 36v in series to get 72v.

Hi, A single battery all has this function ,BMS will balance the voltage.

Yes, you can connect 6pcs in parallel and no more than 10pcs, or you can connect 3 x 200ah battery in parallel.

Hi, thanks for your question. Yes, of course, our 100AH battery can handle 300amps for up to 5 seconds.100AH battery low temp cutoff can handle 300amps for up to 20 seconds.

The same : all have low temperature cut-off protection function.

The difference: 100ah weighs only 24.2LB. 100ah Plus weighs 33LB, and the actual current can reach 107ah.100ah consists of 4pcs cells connected in series,100ah plus has 12pcs cells inside, connected 4pcs in series and 3pcs in parallel.

You mean the battery drops down to 13.6 when not on a charger ?Resting state 100% charged it will sit around 13.6 .Charge voltage is 14.2-14.6 .I hope this helps.

Under voltage warning reconnect voltage: 12V
Discharging limit voltage: 10.4V
Over discharge disconnect voltage: 10.4V
Over discharge reconnect voltage:11.6V

Hello,Thanks for your question, it is for safety cutoff for low temperatures.
Low temp cut off protection ( Charge )0℃ ± 4℃ (32°F ± 39.2°F).
Low temp cut off protection ( Discharge )-20℃ ± 4℃(-4°F ± 39.2°F ) see less.

Yes it comes with two 8×1.25x16MM hex bolts.

40a or 50a or higher?Answer:Hi, we suggest you can use 40A, Maximum 100A.

Hello,Vatrer deep cycle battery has built-in 100A BMS to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. With high temp cutting off prevents charging over 167 °F (75°C) and Low temp cutoff protection when charger and discharger.
